The plantar fascia is a band that runs from the heel to the base of the toes. It provides support for the arch of the foot and assists in the biomechanics of walking and running.

Contributing factors

• Over pronation (stretching of plantar fascia)
• Under pronation
• Leg length inequality
• Faulty biomechanics (reduced ankle motion)
• Muscle imbalances (reduced muscle strength)
• Overuse

Symptoms

Localized tenderness can be felt at attachment at the heel or along the arch of the foot noticed during and after running. Symptoms are worse with weight bearing after a period of rest or immobility (first step in the morning).

Treatment

• Ice
• Rest
• Stretching (plantar fascia and calf muscles)
• Night splints (91% success after 12 weeks)
• Orthotics (correct foot mechanics)
• Avoid uphill and speed work
• Evaluate footwear
• Identify and address training errors
